The design and rig testing of a lean premixed, low emissions, gas turbine combustor prototype are described. The combustor evaluated was a 90 degree sector of a full-scale annular combustor for a 3.7 Mw, natural gas-fired, industrial gas turbine. The combustor sector represented an intermediate development step in extending the lean premixed combustor technology from a can combustor configuration with a single fuel injector to an annular geometry with multiple injectors. In a parallel effort, a rich/lean combustor sector was also evaluated. This effort provided a direct comparison of the NO{sub x} reduction capabilities of the rich/lean and lean premixed concepts. Testing at typical gas turbine operating pressures (122 psig) demonstrated that both the lean premixed and rich/lean combustor sectors were capable of meeting the program NO{sub x} goal of 25 ppm (15% O{sub 2}) while maintaining CO emissions below 50 ppm. The testing indicated that variable geometry and fuel staging will be required for low emissions range extension and low part load operation, respectively.
